Abstract

Recently, contra-rotating propellers (CRP) having higher efficiency draw much attention since the EEDI regulation of IMO has been enforced. In this paper a numerical method based on the vortex lattice potential theory with a wake model and an experimental procedure with a newly built measuring device, specifically focusing on CRPs, are introduced. And they are applied to a series of CRP known to be designed for the purpose of improving EEDI. The numerical and experimental results showed good agreement explaining the characteristics of the CRP properly. The proposed method is believed to be effectively used for various CRP related studies.

IMO가 도입한 Energy Efficiency Design Index (EEDI)의 강제로 최근 관심이 증가되고 있는 상반회전 프로펠러(Contra-Rotating Propeller, CRP)의 단독 상태에서의 성능평가를 위한 보오텍스격자법(Vortex Lattice Method) 기반의 포텐셜 수치해법과 모형시험법을 확립하고 이를 특정 CRP에 적용하여 유용성을 검증하였다. 대상 CRP는 EEDI 개선을 목적으로 설계된 것으로 그 성능을 본 연구의 수치 및 실험 해석을 바탕으로 분석하였다. CRP의 설계점을 포함한 주 작동 영역에 대해 계산과 실험이 좋은 일치를 보임을 확인하였고, 본 연구를 통하여 제안된 기법은 향후 CRP 설계 및 성능해석에 유용하게 사용될 수 있으리라 생각된다.
